SUMMARY
The discussion focuses on finding the instantaneous rate of change of the volume (V) of a sphere with respect to its radius (r) when r equals 5 micrometers. The volume formula used is V = (4/3)π(r^3). The correct approach involves taking the derivative of this formula, which results in dV/dr = 4πr^2. Evaluating this derivative at r = 5 micrometers yields a non-zero value, confirming that the rate of change is not zero.
